How to determine the flow rate of the multi-media filter backwashing pump? 1. the backwashing strength of anthracite is 10 L/m2 * s, quartz sand is 15 L/m2 * s, and 12L/m2 * s is taken in multiple media.2. multiply the counter-washing strength q by the filter area of the equipment to get the counter-washing flow. the counter-washing head is generally> 15mH2O. Considering the pipe resistance and pressure loss, it is recommended to choose a 25 m head pump.The strength of the reverse wash is 10L/m2 * s, which is expressed by q. The backwashing flow is equal to the backwashing strength q multiplied by the filter area of the equipment, so that the pump flow can be obtained. 1. multi-media filters use one or more filter media to pass water with high turbidity through granular or non-granular materials of a certain thickness at a certain pressure, in order to effectively remove suspended impurities and clarify the water, the commonly used filter materials include quartz sand, anthracite coal, manganese sand, etc.,
Knowledge of basket filter standards Has anyone thought about how the water we drink every day guarantees its cleanliness? How to ensure that the water we drink can completely remove harmful substances? Or our gasoline, how to remove some particulate matter, the rest of the parts that can be used? When these things we use need to be filtered before they can be used, the rabbit introduces the standards of the basket filter to see how high the requirements of the basket filter are!Basket filter standardBasket filter manufacturing standard for pipeFlangeMain technical parameters for the main purpose of the connecting high and low take-over basket filter: housing material: carbon steel, stainless steel (SUS304L/SUS316/sus4l), lining fluorine, plastic (PP, PVC, etc ). material of filter core of coarse filter: filter frame, filter screen is stainless steel. sealing ring material: PTFE. working temperature: carbon steel is-40 ℃ ~ 380 ℃, stainless steel is-80 ℃ ~ Standard for manuf
